I am glad for you to speak unknown languages, although I would rather you prophesied. In fact, prophesying does much more good than speaking unknown languages, unless someone can help the church by explaining what you mean.
My friends, what good would it do, if I came and spoke unknown languages to you and didn't explain what I meant? How would I help you, unless I told you what God had shown me or gave you some knowledge or prophecy or teaching?
